To improve a thermal insulating characteristic of a body of a refrigerator.

A partition wall 5 is integrally formed with an inner box 3, and a front insulating material 10. A left insulating material 23 and a right insulating material 32 are inserted into the partition wall 5. In this case, when foamed urethane is fed through a thermal insulating material pouring inlet 36 of an outer box 1, the foamed urethane is flowed from a rear side to a front side within the partition wall 5. Then, foamed urethane is filled in a thermal insulating material filling part 4 through a slant left thermal insulating material passage 31 and a slant right thermal insulating material passage 34 and the foamed urethane is directly filled in the partition wall 5. Due to this fact, flow of the foamed urethane becomes smooth and void is hardly produced in the foamed urethane, so that a thermal insulating performance of a refrigerator body 1 is increased.
